Flowering characteristics and optimal harvest time for seed of wasabi variety. Daruma, were investigated from Dec. 1995 to June 1996 in film house of Suwon. The number of peduncle was $10.2{\pm}2.29$ and most of the peduncle emerged between Jan. 20 and Feb. 10. Average peduncle length was $124{\pm}29.60cm$ and the peduncle grew most rapidly in the middle of march. Flowering started on Jan. 27 and lasted until June 4 with a peak at march 21 and flowering period was $99{\pm}21.32$ days. Flowers which bloomed later than the middle of March set seed but those bloomed earlier became sterile because days with minimum temperature below freezing occurred until the middle of March. Maturing period was $37.5{\pm}2.60$ days and total seed set was $43.2{\pm}8.77%$ in the natural culture condition. Optimal harvest time for seed was the last ten days of May and seed yield per $m^2$ was $79.0{\pm}19.94g%$(11,177 seeds).

Optimal date to cover plastic film tunnel for hastening the harvest and increasing the yield in asparagus was studied using 2-year-old 'Green tower' cultivar in Jeju. Plastic film tunnel was covered on January 10 and 21, and February 10 and 25 in 2004. The asparagus spear sprouted on March 3 in the control. They emerged earlier by about 2 to 3 weeks in the plots covered on January 10 and 25 than the control. First harvesting was hastened by 3 weeks in the plots covered on February 10 and two weeks in the plots covered on January 25 and February 10 compared to the control. Yield per plant was the highest in plastic film tunnel covered on January 10 and 25. Early harvesting in february in plastic film tunnel covered on January 10 and 25 were 325 and 333 kg/10a respectively with no significant difference between two treatments whereas yield was low significantly in plastic film tunnel covered on February 10 and 25.

Meiobenthic community structure was studied in intertidal mud flat and sand flat of Yeochari in Ganghwado in May and August, 1998. Sixteen groups of meiofauna were found at all study sites in the Yeochari tidal flats. Nematodes were the most dominant animal group among the meiofaunal groups as a whole. Sarcomastigophorans, harpacticoid copepods, nauplius larvae of crustaceans and ciliophorans which were also important components of the meiofaunal community. All of these five faunal groups comprised more than 90% of total meiofauna. The maximum total density of meiobenthos was $5.8{\times}10^6ind./m^2$ at the station of sand flat in August and the minimum density was $4.0{\times}10^6ind./m^2$ at same station in May. Biomass of meiobenthos was $1.5g/m^2$(May), $2.3g/m^2$(August) at mud flat and $1.7g/m^2$(May), $2.6g/m^2$(August) at sand flat. At the station of mud flat in May, the highest density was observed within 1cm in depth of upper sediment and steeply decreased increasing depth of sediment. At the sand flat station in August, the highest density was also observed within 1cm in depth of upper sediment and decreased with depth, while the concentration of the animals at the surface was not conspicuous as the mud flat. The value of N/C(nematodes/benthic harpacticoids) ratio was the highest at the station of sand flat in May and the lowest at the sand flat in August.

The present paper deals with the seasonal changes in abundance and composition of diatoms in the Suyung Bay, Pusan, Korea. This study was carried out from August 1966 through July 1967 As a result of the present study, 123 species of diatoms were Identified. While the highest number of diatoms (2,554,000 cells per liter) was recorded in April of 1967, the lowest number (20,400 cells per liter) appeared in December of 1966. In genera the standing stock of diatoms was high in spring and early fall and was low in late fall and winter. Two genera of the diatoms, Chaetoceros and Skeletonema, occupied a great portion of the diatom population throughout the course of this study. The following genera also appeared abundantly: Asterionella, Eucompia, Leptocylindrus and Nitzschia.

This research was carried out to investigate equilibrium moisture content (EMC) of wood in outdoor locations in Korea. EMC was calculated using Hailwood-Horrobin equation for 73 different locations in Korea using the 1981 to 2010 climate normal data obtained from the Korea Meteorological Admnistration (KMA). Daegu showed the lowest values of EMC (11.5), and the highest EMC values (15.8) was found in Heuksando. Considering the season effect, summer (June, July, August) showed the highest values 15.3, followed by autumn (September, October, November) 13.7, winter (December, January, February) 12.2, and spring (February, March, April) 12.0. Monthly EMC showed the lowest values 11.6 in April and July showed the highest EMC values 16.1. The smallest changes in monthly EMC were found in Jeju island and Heuksando showed the largest values 8.7. A proper wood drying based on average EMC is more required in the regions with larger variation in EMC.
